Blueprint overview/Introduction
ELIOT is "Enterprise Edge Lightweight and IOT" project under Akraino approved blueprint family and part of Akraino Edge Stack, which intends to develop a fully integrated edge network infrastructure and running edge computing applications on lightweight Edge Nodes. ELIOT targets on making the edge node a lightweight software stack which can be deployed on edge nodes which have limited hardware capacity by leveraging lightweight OS, container running environment and container orchestration applications.
In addition ELIOT stack focuses to have infrastructure for edge computing which will enable high performance, high availability, security and reduce latency.
Use Case
IOT Gateway and uCPEs (universal CPE) are the use cases which will be covered
1. IOT Gateway - Many diverse business applications require a converged IoT gateway. In this use case, plan is to support following scenarios:
- IOT sensor application
- AI Camera Application
2. uCPE (SD-WAN) - Enterprise WAN edge use of SD-WAN solutions or universal CPU (uCPE). In this use case, plan is to support following scenarios:
- Integrate tungsten fabric (vRouter in Node and controller in manager)
- SD- WAN demo
Industry Sector : WAN edge, enterprise, diverse IoT applications in various vertical market segments, Carrier
Where on the Edge
Many diverse business applications require a converged IoT gateway. Enterprise WAN edge use of SD-WAN solutions or universal CPU (uCPE)
Business use cases:
1. IoT gateway
- Smart cities
- Smart homes
- Connected vehicles
- Connected farming, agriculture
- Logistics
- Industrial, IIoT
2. SD-WAN, WAN edge, uCPE
- Hybrid WAN
- Hybrid cloud deployment
- BYOD
Overall Architecture
ELIOT Architecture consists of a ELIOT Manager and multiple ELIOT Nodes. The scale of ELIOT (edge) Nodes can range from 1 single node to 10, 100, 10K or more.
ELIOT Manager is the central controller which manages the orchestration, life cycle, management and networking of edge nodes. It can be installed on a bare metal server or cloud VM with Ubuntu 16.04 /18.04 or Cent OS 7.5 version.
The node Kubernetes Master (kubeadm, kubectl, kubelet), Kubeedge-EdgeController, Istio Controller to facilitate auto deploy, high availability , orchestration , self healing of the ELiot Edge nodes.
ELIOT Nodes are Edge compute processing nodes which can be on an IOT Gateway or uCPE hardware or VM's. As the edge nodes can have restricted hardware resources of CPU , Memory etc, ELIOT blueprint will use
lightweight OS -- Linaro by LEDGE , Lightweight Kubelet -- KubeEdge , lightweight container runtime interface -- like containerd. By this we can leverage the core features of OS, K8S, CRI and make the edge node lightweight and efficient edge computing node by executing edge applications on node and reducing the interaction between Central Contoller (Cloud Node) and the Edge Node devices.
To manage the service Istio or Kubeedge-edgemesh can be used.
Many cloud native monitoring applications can be used to collect container matirx and show them in graphical manner, like cadvisor, grafana , prometheus.
